Centauri tower I, an office tower

Same tower as city hall but with some changes

Supports should not be needed
Infill at 30-35% should be fine
I used blue silk PLA from overture

Took 6 hours to print on My Creality CR-10 V2

It looked pretty nice with my other greeble city buildings (you should seriously check out Greeble city sets by Fisk400 on thingiverse)
